Physics Stories for 2007

Physics News Update has the list of their picks for the top 10 physics stories of the year:

“In chronological order during the year: light, slowed in one Bose Einstein condensate (BEC), is passed on to another BEC (; electron tunneling in real time can be observed with the use of attosecond pulses (; laser cooling of coin-sized object, at least in one dimension (; the best test ever of Newton’s second law, using a tabletop torsion pendulum (; first Gravity Probe B first results, the measurement of the geodetic effect—the warping of spacetime in the vicinity of and caused by Earth-to a precision of 1%, with better precision yet to come (

The MiniBooNE experiment at Fermilab solves a neutrino mystery, apparently dismissing the possibility of a fourth species of neutrino (; the Tevatron, in its quest to observe the Higgs boson, updated the top quark mass and observed several new types of collision events, such as those in which only a single top quark is made, and those in which a W and Z boson or two Z bosons are made simultaneously (

The shortest light pulse, a 130-attosecond burst of extreme ultraviolet light (; based on data recorded at the Auger Observatory, astronomers conclude that the highest energy cosmic rays come from active galactic nuclei (; and the observation of Cooper pairs in insulators (”
